Acharakkovai () is a poetic work of didactic nature belonging to the Eighteen Lesser Texts (Pathinenkilkanakku) anthology of Tamil literature. This belongs to the 'post Sangam period' corresponding to between 600 and 900 CE. Acharakkovai contains 100 poems written by the poet Peruvaayin Mulliyaar. The poems of Acharakkovai are written in the Venpa meter. Literature Acharakkovai literally translates to "the garland of right conduct" of a Saiva author, Kayatturp Peruvayil Mulliyar. Acharakkovai shows influences of Sanskrit literature and hence believed to be of a later period than the other poems in the Pathinenkilkanakku anthology.
